[Histochemical demonstration of beta-glucuronidase and leucine aminopeptidase in cultivated aortic endothelial cells (author's transl)].
With the aid of histochemical techniques, the activity of beta-GD, LAP, NADH-D, and LDH of in vitro cultivated calf aortic endothelial cells were compared with the activity of these enzymes in different tumours in vivo. The relative high level of beta-GD, NADH-D, and LDH in the endothelial cells is comparable with the increased activity of these enzymes in invasive growing tumours. The results were discussed in connection with a possible enzymolytic effect during the invasive growth of capillary endothelial cells in course of neovascularization in vivo.
